ARBOR.

SPECIFICATION forming part of Letters Patent No. 750,078, dated January 19, 1904. Application filed April 10, 1903. Serial No. 152,016. (No model.) i i To all whom it may concern.-

Be it known that I, FRANK BARTER, a citizen of the United States, residing at Walpole, in the county of Norfolk and State of Massachusetts, have invented a new and useful Improvement in Arbors, of which the following is a specification. 7

My invention relates to arbors, andmore particularly to those adapted as a support upon which to form coils from strips or ribbons of variousflexible materials.

In such machines for cutting material into strips and winding these strips into coils, as that described in the United States Patent to Lewis F. Fales, No. 723,375, dated March 2 1, 1903, it is very desirable that each of the coils .shall be first wound to a certain depth with sufiicient firmness to form a practically noncollapsible core upon which to continue the winding and that each coil shall during the greater portion of the operation be capable of independent rotation upon the support or ar bor to compensate for variations in the thickness of the material operated upon and also to permit separate manipulation by the workmen in joining broken strips. efiiciency of the operator is greatly increased by an ability to secure all the strips to the arbor simultaneously and by being relieved of the necessity of handling a separate supporting member for each coil.

My invention consists in the attainment of these and various other objects.

In the accompanying drawings, Figure 1 is a broken central vertical longitudinal section through one embodiment of my improved arbor, three strips of material being shown.

as secured thereto. Fig. 2is an enlarged transverse section on the line 2 2, Fig. 1. a similar view showing the securing or contact bar raised preparatory to engaging the shown upon the arbor. Fig. 5 is an'enlarged transverse section on the line 5 5 of Fig. 4. Fig. 6 is a similar view illustrating the prior step after the removal of the contact-bar and Moreover, the.

Similar characters throughout the several figures of the drawings. I

All sections are taken in the direction indicated by the arrows.

The numeral 10 designates the body of the arbor, which is preferably of substantially cylindrical form, though here shown as slightly tapered, the sides diverging fromleft to right, and is provided at each end with a journal 11, adapted to be rotatably mounted in bearings in the machine in which it may be employed. Extending longitudinally of the body is a recess or slot 12, conveniently of rectangular section. From the bottom of the slot opens a suitable number of recesses 13, of which three are here illustrated, each ofwhich is formed with an inclined cam-face 14. Ex-

indicate like parts tending longitudinally of and substantially filling the slot transversely is a bar 15, which, as illustrated, is of uniform thickness radially of the body throughout its length. Upon the inner side of the bar are projections 18, corresponding in number and general form to the recesses 13, except that said projections gradually increase in length as they approach the end of the slot at which the diameter of the body is greatest, the ends of said projections substantially occupying a plane of equal but opposite inclination to that of the body at the opening of the slot. These projections lie within the recesses 13 when the bar is seated at the bottom of the slot, and each has a cam-face 19 cooperating with the face 14. Along the outer portion of the slot extends a bar 20, fitting somewhat loosely therein, so that a slight space may be left at 22 are shown at the end of both bars for engagement by a tool to enable them to be moved longitudinally of the slot by the operator. A pin or member 23 moves in a recess 24, preferably opening from the bottom of the slot, and may be forced normally outward by a spiral spring 25 into a slot 26 in the inner side of the bar 15, the end walls of which slot limit the longitudinal movement of said bar. A spring-clip 27, partly encircling the body, is preferably provided at each end to retain the bars in place. They may be held against displacement, while movable circumferentially from the bars to release them, by screws 28, extending through slots 29 and threaded into the body. For convenience in removing the completed coils from the arbor the screws may be omitted at the smaller end thereof and the clip retai ed in place by its frictional engagement.

In the use of the device, the ends of the clips being moved from'over the slot 12 and the bar 20 raised from said slot, which is preferably caused to lie uppermost, the ends of the strips of material which are to be coiled are laid side by side across the body, Fig. 3. But three of these strips are here illustrated; but it will be understood that practically the entire length of the body maybe employed for the winding. The bar 15 being seated at the bottom of the slot, the bar 20 is forced downward toward it and acts as a securing member to hold by its contact all the strips in positive engagement with the arbor, Figs. 1 and 2, the space between the sides of the bar and side walls of the slot being sufficient to admit them. The arbor is now rotated and the formation of the coils begins, the engagement of the strips with the arbor causing each of these to be tightly wound to furnish a compact core. When the desired depth of core is secured, the bar 20 is withdrawn longitudinally from the slot, its taper allowing this to be readily accomplished, which releases the ends of all the strips from their engagement with the arbor, Fig. 6, and as a result of the projection of the outer face of the bar 20 at 21 beyond the cylindrical surface a slight space is formed between the arbor and the inner turn of the coils sufficient to permitpractically free rotation of the latter upon their support. To fill the slot and givea continuous surface suitable for the winding and the independent rotary movement of the coils thereover, the bar 15 is drawn longitudinally of the slot by the operator, so that the cam-faces of its projections 18 ride up the faces 14 of the barrecesses. This moves said bar outward toward the position occupied by bar 20 until the ends of the projections rest upon the bottom of the slot, when further movement is stopped by the contact of the pin 23 with the end wall of the slot 26, Figs. 4 and 5. This brings the curved outer face of the bar into the cylindrical surface of the arbor or flush therewith throughout the entire length of the former, since the difference in the length of the projections compensates for the taper of the body which provides for the free removal of the finished coils therefromand also for the taper of the outer bar 20 without rendering its outer edge unsymmetrical with relation to the cylindrical surface. With this filling member in place the arbor presents a substantially smooth and continuous surface, upon which the winding may continue to the best advantage. When the coils are completed, they may be readily removed from the arbor without the detaching of any portion thereof. To prepare the arbor for the forming of another set of coils, it is only necessary to slide the filling-bar back until its projections occupy the recesses 13, when above-described operations may be repeated.

Having thus described my invention, I elaim 1. The combination with a support upon which material is to be wound, of a member carried by the support within the coil of material and adapted to be removed therefrom while the coil is upon the support, and a second member movable toward the position 0c cupied by the first member.
